Hey, Lettie.

I am a loyal Boysen customer. We recently scraped and repainted the exterior of our house with Acrytex. Our roof is painted with Roofgard and all our interiors are Healthy Home and Quick Drying Enamel.

I need your advice for our water tank. We have a 2,000-liter polypropylene water tank that we have had for 4 years. The manufacturer has recommended that we paint it. I searched on the internet and it said we can use 100% acrylic paint on plastic. I was thinking this would be either Permacoat or Elasti-kote and in the color white to account for sun exposure.

Would you please provide your recommendations? Thank you so much!

Hi, Boysen User R.

Thank you for your message. We appreciate your enthusiasm for our products! We do our best to provide you with reliable high-quality paints that meet, and even exceed, your expectations.

Now, for your polypropylene water tank. Unfortunately, we DO NOT recommend any of the two Boysen products you mentioned for your project.

Paint TechTalk with Lettie: Can I Use Boysen Permacoat on My Plastic Water Tank? | MyBoysen

You’re right that Boysen Permacoat Latex and Boysen Elasti-kote are 100% acrylic paints! However, they are both formulated for use on concrete only. We cannot guarantee that they will perform as intended on surfaces they’re not meant to be applied, like on plastic.

We also, as of now, do not carry paint for plastic surfaces. Sadly, your water tank may not be painted with a Boysen product today. Maybe in the future when we do come out with one that will have the same excellent quality as the Boysen products you already trust.

In the meantime, wishing you luck with your water tank! Hopefully, you find a solution that fits your needs.

Your painting partner,
